Cone-bine CT(CBCT)images of 2 130 maxillary third molars were divided into 3 groups according to the impaction position. The relationship between the floor of maxillary sinus and the roots of maxillary third molar was analyzed and compared.In low,median and high impaction groups the probability of the root tip of maxillary third molar higher than the floor of maxillary sinus was 4.5%,10.3% and 14.6% respectively.

AIM: To investigate the effects of oral administration of Astragalus membranceus, mung bean and arsenolite on the toxic of the arsenolite induced rats and the possible mechanisms with metallothionein (MT). METHODS: All the rats were oral administration with arsenolite. The Astragalus membranceus and mung bean were compared with the cadmium chloride which induced MT synthesis. The contents of MT were determined by cadmium saturation method, the liver mRNA levels for MT 1, MT 2 were detected by RT PCR. The protective effects of renal and liver were observed by testing alanine aminotransferase (ALT), blood urea nitrogen (BUN) and serum creatinine (SCR). RESULTS: The contents of MT were accorded with the mRNA expression of MT 1, MT 2. Arsenolite, Astragalus membranceus and mung bean could induce the synthesis of MT, but the contents of MT which arsenolite induced were trace. The contents of MT significantly increased after oral administration of Astragalus membranceus and mung bean, especially in the Astragalus membranceus group (P

The Chinese acupuncture doesn't only belong to China but rather to the world.The boom of overseas acupuncture education and scientific research as well as the satisfactory working environment compels us to reflect the Chinese traditional medicine education in our country.Especially in higher education specialty courses of acupuncture should not be subdivided;meanwhile,much attention should be paid to elementary education of western medicine.

Objective To investigate the impact of isoniazid (INH)-resistant Mycobacterium tuberculosis (Mtb) on the prevalence and dissemination of multi-drug resistant tuberculosis (MDR-TB).Methods A total of 251 patients diagnosed with tuberculosis in designated hospitals of Guanyun,Jiangsu and Deqing,Zhejiang from 2010 to 2011 were included in the study.The drug susceptibility tests (DST) were performed on all the Mtb isolates available from the sputum cultures.Mycobacteral interspersed repetitive units-variable number tandem repeats (MIRU-VNTR) was conducted for genotyping for all available Mtb isolates.Chi-square test,Fisher exact test,ANOVA and non-conditional Logistic regression modelling were applied for data analysis.Results Among 251 patients with Mtb isolates and DST results available,72 (28.7％) were resistant to INH,including 13 were INH mono-drug resistant.Of the remaining 59 INH-resistant Mtb,34 (13.5％) were resistant to rifampin TB and 25 were resistant to streptomycin and/or ethambutol.The clustering analysis based on MIRU-VNTR genotyping revealed 29 clustered genotypes (including 105 isolates) and 146 unique genotypes (including 119 isolates).Twentyfive clusters contained drug resistant Mtb and 16 clusters of them comprised by 37 INH-resistant isolates and 20 MDR-TB isolates,which accounted for 51.4％ of the INH-resistant isolates and 58.8％ of the MDR-TB isolates.Single factor analysis showed that sex,age,previous tuberculosis treatment history and sputum smear results were all related to INH-resistant tuberculosis and MDR-TB (all P ＜ 0.05).Multiple factors analysis showed that previous tuberculosis treatment history was risk factor of MDR-TB (OR=8.40,95 ％CI:3.342-21.105),while the risk factors of INH-resistant tuberculosis were previous tuberculosis treatment history (OR=3.52,95％CI:1.570-7.910),pulmonary caviry (OR=2.27,95％CI:1.075-4.799) and sputum smear results (OR=0.50,95％CI:0.275-0.892).Conclusions That INH-resistant strain may evolve to the MDR-TB after recent transmission is a possible trend.Patients with previous treatment history and advanced age are at high risk of INH-resistant tuberculosis and MDR-TB.

Objective To evaluate the efficacy and safety of endoscopic retrograde cholangiopancre-atography (ERCP)by using a duodenoscope in patients with prior Billroth Ⅱ gastrectomy.Methods Data of 98 patients(including 7 who underwent Billroth Ⅱand Braun)with prior Billroth Ⅱ gastrectomy who un-derwent ERCP from January 2008 to May 2014 at Endoscopy Center of Ruijin Hospital were retrospectively studied.Results A total of 98 patients accepted 111 ERCP procedures,the overall success rate was 75.7%(84 /111).The success rate of accessing Vater′s papilla was 82.0%(91 /111)and the selective can-nulations success rate was 92.3%(84 /91).In the cases of successful access,therapeutic procedures were achieved in 100.0%(84 /84)of all patients.The overall rate of complications was 4.5%(5 /111),with mild post-procedure pancreatitis occurring in 3 cases,cholangitis in 2 cases,respectively.Conclusion ERCP u-sing a duodenoscope can be safely and effectively performed in patients with prior Billroth Ⅱ gastrectomy with high cannulation and treatment success rates.

BACKGROUND:Clinical y, bone marrow mesenchymal stem cel s combined with artificial bones for early osteonecrosis of the femoral head have a wonderful outcome.
OBJECTIVE:To review the biological properties of bone marrow mesenchymal stem cel s and to summarize the application progress of bone marrow mesenchymal stem cel s combined with different artificial bones in the treatment of early osteonecrosis of the femoral head.
METHODS:PubMed (2003-2013), FMJS (2003-2013), Wanfang (2005-2013), CNKI (2005-2013) and CBM (2005-2013) databases were retrieved by computer using the keywords of“bone marrow mesenchymal stem cel s;artificial bone;osteonecrosis of the femoral head”in Chinese and English.
RESULTS AND CONCLUSION:It wil lower the pressure of the femoral head, accelerate repair of the blood capil ary, improve the blood supply, osteoblast proliferation and differentiation, and thus delay or even prevent artificial joint replacement after osteonecrosis of the femoral head by applying bone marrow mesenchymal stem cel s combined with different artificial bones, such as corl ine hydroxyapatite, calcium hydroxylaptite, biological ceramics and calcium sulfate bones. But now, there are stil a lot of problems which need to be solved, including pathological mechanism underlying bone marrow mesenchymal stem cel s for treatment of osteonecrosis of the femoral head, obvious difference between the quantity and quality of seed cel s because of individual difference, different sites and culture techniques. So, artificial bone materials are under review, and large-sample randomized control trials are required. Its long-term outcomes also lack for fol ow-up observation, as wel as there is no a unified quantitative standard for the appropriate selection of indication, curative effect evaluation and the awareness of the operation.

OBJECTIVE Apolyclonalantibody-basedhomogeneouschemiluminescenceimmunoas-say was developed and optimized using AlphaLISA technology for the quantitative detection of microcys-tin-LR(MC-LR)inwatersamples.METHODS Thismethodwasbasedonacompetitivemodelin which an immune complex was formed from the ingegral binding of artificial MC-LR antigen-coated lumi-nescene beads,free MC-LR standards or sa mples,antibody and biotinylated second antibody.Next sensor bead were added that approached the i mmune co mplex through biotin-streptavidin interaction. With the exciting light,the energy was passed from the sensor luminescer before a special emission light could be observed.To opti mize the reaction conditions,working dilutions of polyclonal antibody and bioti-nylated second antibody were assayed while the effect of buffer syste ms and ti me of each reaction were evaluated.RESULTS Maininfluencingfactorsoftheassaywerediscussedasworkingdilutionsofpoly-clonal antibody and biotinylated goat anti rabbit IgG,assay buffer and reacting ti me.After opti mization of reaction conditions,MC-LR AlphaLISA could be finished in 40 min,with a sensitivity of 0.006 μg·L-1 and a dynamic range of 0.006 -5 μg·L-1 .The coefficient of variation was below 10% and average recovery was 1 07.7%.Moreover,the cross reactivity rates of MC-RR and MC-RY to MC-LR were 13.2%and0.91%,respectively.CONCLUSION Thismethodishighlysensitiveandspecific,time-saving and quite suitable for high throughput determination of MC-LR water samples.
